Question

Hi friends plz answer for all these questions correctly if you know answer it otherwise don't answer it​

Answer 1

Explanation:

1) Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

2) Newtown / coulomb or volt per meter

3) Field line is a locus that is defined by a vector field and a starting location within the field. For the electric fields, we have electric field lines. As we have seen in Electrostatics, electric charges create an electric field in the space sorrounding them. It acts as a kind of "map" that gives that gives the direction and indicates the strength of the electric field at various regions in space. The concept of electric field lines was introduced by Michael Faraday

4) Some properties of Electric Field line are: Electric field lines always begin on a positive charge and end on a negative charge, so they do not form closed curves. They do not start or stop in midspace

The number of electric field lines leaving a positive charge or entering a negative charge is proportional to the magnitude of the charge.

Electric field lines never intersect.

In an uniform electric field, the field lines are straight, parallel and uniformly spaced.

The electric field lines can never form closed loops, as line can never start and end on the same charge.

These field lines always flow from higher potential to lower potential.

If the electric field in a given region of space is zero, electric field lines do not exist.

The tangent to a line at any point gives the direction of the electric field at the point. Also, this is the path on which a positive test charge will tend to move if free to do so.

hope you find this answer satisfactory

Answer 2

Answer:

Hey mate here is your answer,

1. Electric field:

If a particle has an electric charge and is an electric field. It is an vector field. Electric fields are generated by charges.There is an external electric field in a current carrying conductor.

2. I think unit of Electric Intensity is may be Volt/meter (V/M).

Sry mate,I know only 2 questions.

I have tried my best to answer your questions.

Have a great day....
